Describe Event, Problem or Product Use Error: “Over a period of several days prior to severe episode, I experienced strange swellings on my face. I mentioned them to my doctor, who believed they were related to herpes type 1. I did not agree, as I never had herpes on my chin or cheek. Symptoms spread to strange swellings on my calfs, 1/2\”” wide by 3\”” long, which itched. This culminated in a night where I experienced itchy whelts all over my torso, plus a rash on my arms and legs. I took an antihystamine and tried to sleep, but awoke with my tongue so swollen I could hardly breathe. I forced a pseudoephedrine past my tongue, which reduced the swelling enough for me to decide against an expensive trip to the emergency room. When my doctor\’s office opened that morning, I was there and received treatment.”
